- BURNER.

Application filed April 2,6,

To all whom z'z may concern: v

Be lit known that l, JOHN O. CARREY, a citizen of the United States, residingv at the city yof St. Louis and State of Missouri,l have invented a new and useful Burner, of which the following is a specification.

This invention relates to improvements in burners and/consists in the novel construction hereinafter disclosed.

An object of the invention is to provide an improved burner whereby continuous combustion may be ,maintained for the operation of engines and other purposes.

Another object of the invention is to provide a burner including an air passage, a fuel passage, a mixing chamber, and a burner nozzle whereby combustion may be maintained for the purpose of supplying pressure for the operation of engines and other purposes. Y

With the foregoing and additional advantages in construction in view, l have designed the burner hereinafter described, reference being made tothe accompanying drawings, in which lligure l is a side elevation of a burner and combustion chamber in which continuous combustion may be maintained.

Fig. 2 is a vertical sectional view thereof,

Fig. 3 is a cross sectional view on the line 3dS of Fig. 2.

As shown in the drawings, the device is mounted in connection with a combustion chamber A and from the following description it will be understood that the invention is adapted for use or practice in the operation of either rotary or reciprocating or heat engines, or in combustion chambers, furnaces, or for other purposes.

As shown, the chamber l is secured to the engine casing and supports a clamp device 2 by which the burner nozzle 3, preferably of non-metallic refractory material, is supported. As shown, the burner nozzle is formed with a circumferential flange 4 clamped between the clamp 2 and the end of the chamber l.

Air is admitted into the chamber lthrough a passage 5 terminating in a nozzle 6 within the burner nozzle 3. The fuel is admitted into the chamber l through a passage 7 which opens above the upper end of the burner nozzle and above the lower end of the nozzle 6. Thus, thefuel is drawn from the passage 7 into the burner nozzle Specification of Letters Patent. Patented Aug'. 10, 1920.

1919. Serial No. 292,934.

S by the rush of air forced through the passage 5 and the nozzle 6, creating a suction for the fuel; i

IThe construction and arrangement of the parts shown may be varied without departure from the invention and l do not restrict myself to the specic device shown and described. y

lll hat I claim and desire to secure by Letters Patent, is

l. The combination with a chamber having an exteriorly recessed opening through the wall thereof, of a tubular burner nozzle extending through the opening and projecting on both sides of the chamber wall, a flange on said nozzle, a clamp device seated in the recess and engaging said flange for supporting said nozzle, a casing connected with the wall of the `chamber and inclosing the upper end of said burner nozzle, an air passage entering said casing and overlapping the inclosed end of the burner nozzle, and a fuel supply passage entering Vsaid casing and arranged so that the suction of the air escapingfrom said air passage will withdraw fuel from said fuel passage and force the` mixture into said chamber.

2. The Vcombination of Va casing having an opening therein, a tubular burner nozzle having flared ends mounted in said opening and extending On both sides of the wall of the casing, means for removably supporting the burner nozzle in said opening, a tubular air passage of a less diameter than the burner nozzle extending into the outer end of saidburner nozzle, a casing forming a chamber supported by said first` named casing and inclosing the air passage and the end of the burner nozzle, and a fuel supply pipe entering said chamber above the'upper end of the burner nozzle.

3. The combination of an air pipe having a restricted nozzle at its end, a tubular y los' closing the upper endY of said burner nozzle,

a clamping member hearing' against 'the flange on said burner nozzle for support- Y ing the saine inpostion, an air passage entering said easing Vand overlapping the nolosed end of the burner nozzle7 and a fuel supply passageentering said easing at a point so 'thatthe suction of the air escapingfroni said air passage Will Withdraw fuelfroin'sad fuel passage. p'

5;' The' combination' With a ohamber'having an opening therein and a recess enibracingtheV outerend of saidope'ning, of a tubular burner nozzle of refractory material, having an external flange, said nozzle extending through said opening and projeoting beyond the inner' and outer surface of the Wall of the chamber, a'easng inelosthe upper end of said burner nozzle, said casing having a threaded portion extending into said recess, a Clamping Inember adapted to be threaded over said eX- tending end'ofsaid casing and to Clamp the Aflange of the nozzle, whereby the nozzle is supported in' 'position' in said opening,v an air passage enteringsaidjoasing and overlapping' the inclosedfend-Y of the burner nozzle,` and afuel supply passage extending into said4 easing-at an angle in respect;

of the airf passage.
